Title: Oil-pressure control valve
IPC: G05D16/10
Filed: 1967-09-15
Abstract: 1,194,028. Valves. LICENTIA PATENTVERWALTUNGS G.m.b.H. 15 Sept., 1967 [16 Sept., 1966], No. 42091/67. Heading F2V. [Also in Division G3] An oil pressure control valve comprises a piston 2 displaceable in a housing 1 against a spring 7, and a further piston 8 located inside the piston 2 and loaded by a spring 9 to control flow through apertures 13, 14 in response to pressure at an aperture 12. In operation, upon an increase in a control oil pressure in chamber 19, piston 2 is moved downwards to increase the aperture in flange 15 and reduce the pressure of a controlled oil in the chamber 18, through outlet 3, which is transmitted to the chamber in piston 2 via aperture 12. The reduced pressure allows piston 8 to be moved upwards by spring 9 to uncover port 13, which relieves the pressure in the chamber 19 via apertures 13, 14, and outlet 4, to halt the downward movement of the piston 2. The force of the spring 9 can be adjusted by a screw 10. In Fig. 2, (not shown), downward movement of the piston 2 reduces the size of the aperture in the flange 15, to increase the pressure in chamber 18, which forces piston 8 downwards, to relieve chamber 19 via aperture 13, and a passageway 21 in the piston.

Title: Improvements in or relating to fluorinated organic compounds
Inventor: TATLOW JOHN COLIN
IPC: C07C23/10
Filed: 1961-11-27
Abstract: A monocyclic polyfluoroalicyclic compound having conjugated unsaturation including one or two groups of formula =CR1R2, which may be the same or different, connected to nuclear carbon atoms is prepared by dehydrohalogenating by 1,4-elimination a corresponding compound of the formula <FORM:1041781/C2/1> wherein X is fluorine or an a -haloalkyl group, R1 and R2 are each hydrogen, fluorine or alkyl, and the radical CR1R2 contains a maximum of 5 carbon atoms. The invention also comprises the compounds 3-methylene-octafluorocyclohexene, 1,2-bis(methylene)-octafluorocyclohexane, 1,2-bis(difluoromethylene)-octafluorocyclohexane and 1-methylene-2-difluoromethylene-octafluorocyclohexane. Examples are given. 1-Trifluoromethylperfluorocyclohexene may be methylated with methyl lithium to give the corresponding 1-trifluoromethyl-2-methyl compound which may be chlorinated to give 1,2-dichloro - 1 - trifluoromethyl - 2 - dichloromethyl-octafluorocyclohexane; after removal of the nuclear chlorine substituents to regenerate the double bond the dichloromethyl group is converted to difluoromethyl by the action of a fluorinating agent such as SbF5.  Treatment of decafluorocyclohexene with methyl lithium gives 1-methyl-nonafluorocyclohexene and 1,2-dimethyl-octafluorocyclohexene; treatment of the latter compound with chlorine gives 1-chloromethyl-2-methyl-octafluorocyclohexene.ALSO:Polymers may be obtained by polymerizing monocyclic polyfluoroalicyclic compounds having conjugated unsaturation including one or two groups of formula -CR1R2 connected to nuclear carbon atoms, the compounds being obtainable by dehydrohalogenating by 1,4-elimination the corresponding compounds of the formula <FORM:1041781/C3/1> wherein X is fluorine or an a -haloalkyl group, R1 and R2 are each hydrogen, fluorine or alkyl, and the radicals CR1R2 are the same or different and each contains a maximum of 5 carbon atoms. The polymerization may be initiated by free-radical initiators, heat or ultra-violet irradiation. If the preparation of the monomers is carried out by heating for an extended period with an alkali metal fluoride the monomer polymerises in situ to form the same kind of polymer as produced by the above methods.  This product, by further loss of one molecule of HF per unit of polymer chain, is converted to a highly conjugated polyene.  Examples describe the preparation of polymers of 3-methylene-octafluorocyclohexene and 1,2-bis(methylene)-octafluorocyclohexane.
